When is the Ubuntu stock image going to be updated?

This question is in reference to Atlassian Documentation: stock images

The Ubuntu stock image for Bamboo AMI is based on Vervid, which was EOL'd in Feb. 2016 (https://lists.ubuntu.com/archives/ubuntu-announce/2016-January/000203.html). It should be pointed out that basing the image on a non-LTS release was painfully short-sighted. The 16.04 release, Xenial, will be supported until 2021, which would be an ideal update for Ubuntu stock image. Any chance this could be expected in the near future?
